Title: Method for transferring data packet and device therefor
Inventor: BURMEISTER CARSTEN
IPC: H04L1/00
Filed: 2001-09-06
Abstract: PROBLEM TO BE SOLVED: To improve both compression efficiency and robust performance in a method and device for transferring a data packet having a compressed header on a transmission path. SOLUTION: At the time of compressing a header by using contexts, and then transferring a plurality of continuous updated packets including data indicating the contexts, transmission path quality is decided (620), and the number (m1) of the continuous updated packets to be transferred is set according to this transmission path quality (640). The transmission path quality is decided by measuring a block error rate (BLER) or an SN rate(SNR). Also, the transmission path quality is estimated by judging whether or not a negative response message is received. Moreover, the total number of the updated packets and the non-updated packets to be transferred at the time of the update stage of the contexts is set according to a round trip time. Also, the number of the continuous non-updated packets to be transferred is searched for based on coder/decoder characteristics.  Thus, this data packet transfer method is made valid for its use on a transmission path whose reliability is not guaranteed, for example, a radio transmission path.

Title: Rod coating apparatus and rod coating method
Inventor: KOMINAMI HIDEAKI
IPC: B05D1/28
Filed: 2001-09-07
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of a scratch in a web by allowing the running speed of the web to coincide with the rotational speed of a rod in a short time after the contact of the rod with the web. SOLUTION: The web 12 is coated with the coating solution of the liquid sump formed between the rod 14 and the web 12 by bringing the rod 14 into contact with the web 12 to rotate the same so as to follow the running of the web 12. The rod 14 is forcibly rotated by a drive motor 46 and the rotatory force of the drive motor 46 is transmitted to the rod 14 or cut off by the one- way clutch 32 provided to a drive shaft 48 so as not to apply a scratch to the web 12 when the rod 14 comes into contact with the web 12. Therefore, when this coating apparatus is compared with a conventional coating apparatus, the rotatory force from the drive motor 46 is cut off in a real time and, therefore, the running speed of the web 12 coincides with the rotational speed of the rod 14 in a short time.  As a result, even if the web 12 is allowed to run at a high speed, no scratch is generated in the web 2 during coating due to the rod 14.

In the case of scanning, since the internal shut-off plate 23 shuts off the space between the discharge port 5 and the read position, incidence of an external light onto the read position can be prevented.  Even when the internal shut-off plate 23 is pushed opened, the outer shut-off plate 24 shuts off incidence of an external light.
